Allergies can affect your sleep and are even associated with sleep apnea. So why is this? When you sleep at night, most people breathe mostly through their nose, but allergies can cause swelling and irritation of the nose that limits the amount of airflow through the nose. And that leads to you, opening your mouth and breathing through your mouth, which can dry out your mouth.

It can cause you to wake up and overall it can lead to poor quality sleep. So, this has been shown in a 2017 study in the journal of clinical sleep, where they saw that 30% of their patients with obstructive sleep apnea also had allergies. So we know there's an association and fixing one can certainly improve the other.
